The present invention relates to a wireless communication technology, and more particularly, to a super frame structure for providing a seamless communication service to a narrowband mode terminal and a data communication method using the same.

In addition, the present invention relates to a problem when based on Cognitive Radio (hereinafter referred to as "CR") which is one of wireless transmission techniques for efficiently using frequencies in the future, and the conventional communication scheme and The CR-based communication method is described below.

Currently operating wireless communication services are usually implemented to transmit and receive data using a fixed bandwidth. In particular, in the case of a mobile communication system, a method of obtaining maximum performance through frequency allocation between cells using a resource allocated to a specific band is taken. The technique of transmitting and receiving signals using a fixed band has a fixed framework in that manner, and it is possible to increase the quality of service (e.g., improve throughput or provide a service according to the current system specification). Increasing the number of users that can be served, etc. is usually broken down into smaller cell structures, or by extending existing system specifications on demand and installing new infrastructure.

Up to now, the method of using frequency resources has mainly been a service method using a fixed bandwidth and a service method using a scalable bandwidth selectively applying various bandwidth options. When using a fixed bandwidth system, a standardized framework and service is applied by applying various transmission / reception techniques appropriate to the band, and the burden of changing the entire service system in any change to the specification is applied. Have On the other hand, the standard that utilizes variable bandwidth is designed to make it easier to control the change of bandwidth and the quality of service than the case of fixed bandwidth, but in actual service operation, the variable bandwidth service works the same as the fixed bandwidth service. That is, what is obtained by using a variable bandwidth is a technique for changing the quality of service without increasing the complexity of hardware by using the same technique without changing the technology used as the bandwidth is widened or narrowed.

Separately, the CR technique appeared, which was proposed in 1999 by Mitola, with the intention of using the frequency band more efficiently. CR is basically implemented based on software defined radio (SDR), and the spectrum is searched and selected as an unused spectrum to be set as the default communication band, or according to the type of service found in the SDR architecture. Modifications can be made at the discretion of changing the type of service or changing the quality of the service. Considering the basic concept and various wireless services currently in operation, it is determined that the wireless terminal to be carried by each individual in the future will be one converged form, which is expected to be suitable for the CR terminal. This CR technique is currently adopted as a technique to provide WRAN service by sharing TV band in IEEE 802.22 during standardization, and is implemented as protocol setting through frequency sensing under the name of coexistence.

As described above, if the communication method according to the frequency management scheme, which is currently discussed, can be divided into 1) fixed bandwidth communication method, 2) variable bandwidth communication method, and 3) CR-based communication method, The following briefly describes with reference to the drawings.

1 is a diagram illustrating a fixed bandwidth service method.

First, the fixed bandwidth service scheme currently provides a service using a bandwidth determined in an initial standardization stage such as a mobile communication system (CDMA or GSM), a wireless LAN (802.11 or HiperLAN), and a wireless PAN (802.15). This service bandwidth is licensed by the government or is used in a fixed amount for the open frequency band. The characteristic of this service is that there is no increase or decrease of the frequency bandwidth over time as shown in FIG. 1, and the service within a predetermined bandwidth is optimized in the bandwidth. Figure 1 illustrates the continued use of a predetermined bandwidth in this way regardless of the amount of current traffic.

2 and 3 are diagrams for explaining a variable bandwidth service method.

The variable bandwidth service scheme may be divided into two types as shown in FIGS. 2 and 3, respectively. They are in a format in which the bandwidth used by the terminal is variable while the service band of the base station is constant, and in a format in which the bandwidth used by the base station is also variable. First, an example of a case where a bandwidth used by a base station is fixed and a bandwidth in which a terminal receives a service is variable is illustrated in FIG. 2. Examples of this service include services such as 802.16, 802.20, or 3GPP LTE using OFDM, and EV-DO or EV-DV, which is a method of allocating channels to a terminal in the CDMA scheme. These services are determined by the total bandwidth used by the base station, the bandwidth used by the terminal is a method of accessing the service by being assigned a specific bandwidth from the base station. In this case, the bandwidth to be used by the base station is determined at the time of system installation.

On the other hand, as shown in FIG. 3, the bandwidth serviced by the base station may be changed according to time. This case is a service model generated by accepting CR in 802.22. That is, it detects the available spectrum at each time and the base station expands its service within the available bandwidth. At this time, the requirements of the terminal should be able to accommodate the bandwidth as well. 3 exemplarily illustrates how a frequency band used by a base station and a terminal changes with time.

In IEEE 802.22, WRAN services are provided while sharing a TV band, and a service unit is determined by an integer multiple of available TV channels. That is, if there is an unused TV channel identified by the base station, this channel is used for the WRAN service. If the TV channels are continuously available within the range set forth in the standard, these channels are bundled and used as one band, and at this time, the entire service is provided. The terminal should grasp all such channel conditions of the base station and likewise increase its reception capability.

4 is a diagram illustrating a CR based service scheme.

CR basically does not specify a particular technique. Only to change the configuration of the terminal according to the spectrum resources in order to use the current spectrum resources more efficiently is called CR. 4 shows how the CR terminal approaches when there is no use in the spectrum. If there is a spectrum band to be observed and an unused area is found in the band, a communication service to be implemented as a CR is provided within the area. This service may be a fixed band service or a variable band service. The only difference from existing services is that the spectrum used varies over time, requiring a protocol and learning process to manage it. The current standard for implementing CR is the 802.22 WRAN system.

Meanwhile, descriptions of the super frame and the frame structure used in the IEEE 802.22 system are as follows.

5 and 6 illustrate a super frame and a frame structure used in the IEEE 802.22 system.

The super frame consists of a PHY preamble, a superframe control header (SCH), and a plurality of frames, as shown in FIG. 5. The preamble is specific sequence data located in the first symbol of every super frame. The preamble exists for each TV channel, and the CPE is used to synchronize the base station BS. In addition, the SCH includes information on the super frame, the system type available in the current band, the number of super frames, the number of frames included in the super frame, whether the channel is combined, the information about the quiet period, etc. It consists of. Lastly, the frame is a data sequence channel for a certain period of time due to physical characteristics. The frame includes a downlink subframe and an uplink subframe, and one superframe includes 16 frames (10 ms).

On the other hand, as shown in Figure 6, the frame is composed of a preamble, a Frame Control Header (FCH), a burst (burst), etc. Other than that shown in Figure 6, but generally the same symbol interval as the FCH DL-MAP located in the channel region of the UL, UL-MAP located at the start of the first burst, and other MAC messages indicating the physical characteristics in the downlink / uplink channel includes a DCD / UCD. The preamble is specific sequence data located at the first symbol of every frame, which is used by the mobile station (MS) to synchronize with the BS. The DL-MAP / UL-MAP is a MAC that informs the UE of channel resource allocation in the downlink / uplink. Message. In addition, the burst is a unit of data transmitted or received to one terminal, the size and position of the burst is reported in the above-described DL-MAP / UL-MAP message.

Meanwhile, when a single channel CPE enters a network newly in a system using such a super frame and frame structure, a conventional method will be described below.

7 is a diagram illustrating a conventional notification process for providing a service to a CPE for single channel mode.

The IEEE 802.22 system is capable of multi-channel combining, and the base station changes the super frame structure according to the performance of the CPE. For example, referring to FIG. 7, in the broadband mode CPE, data from a frame in which three unit channels (for example, unit channels t-1, t, t + 1) are combined into one in an Nth super frame. Received. Each terminal can decode superframe preamble and SCH for each channel. If the terminal to enter the network is a CPE of a single mode, the UE transmits that the CPE entered through the Alert Window (AW) is a single mode to the base station. Then, the base station receives the received channel is separated by each channel in the (N + 1) superframe (n + 1) for each channel and transmitted by changing the frame structure to enable a single-mode terminal to service.

Such a conventional communication scheme, that is, a standardization scheme currently in progress, is a fixed terminal and proposes a super frame structure considering a narrowband mode CPE and a wideband mode CPE. However, in the current super frame structure, in order to receive a service from a base station in a narrow frame combined terminal in a super frame in which multiple channels are combined, the super frame transmitted after the base station determines whether the terminal is in a single mode in the current super frame. In the middle of the super frame, that is, the frame period in which data is transmitted from the base station, the narrowband mode terminal cannot receive the service from the base station. This is the case when a terminal in a narrowband mode receiving a service from another channel and attempting to move to another channel, especially a mobile terminal, attempts to enter the network in the middle of the super frame, and then combines the combined channels and then transmits the super frame. There is a problem that the service is disconnected from the base station until receiving.

In order to solve the problems described above, an object of the present invention is to enable seamless communication even in a mobile narrowband terminal by allowing a narrowband mode terminal to receive a communication service within a corresponding superframe period even when the terminal enters the middle of a specific superframe. It is to provide a super frame structure that can provide a service.

More specifically, the location information on the next narrowband mode support frame may include a frame number of the next narrowband mode support frame and a period until the next narrowband mode support frame.

Further, in such cases, the method may further include inserting information indicating a position of the one or more frame regions into the super frame control header unit SCH of the super frame, and included in the super frame control header unit.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The detailed description, which will be given below with reference to the accompanying drawings, is intended to explain exemplary embodiments of the present invention and is not intended to represent the only embodiments in which the present invention may be practiced. The following detailed description includes specific details in order to provide a thorough understanding of the present invention. However, one of ordinary skill in the art appreciates that the present invention may be practiced without these specific details. For example, the super frame structure described in the following description includes not only the structure for achieving the object of the present invention, but also other details for easy implementation by those skilled in the art, but to obtain the desired effect of the present invention. Other detailed configurations can be changed to other configurations as long as they include a structure for doing so. In addition, in the following description, terms such as "terminal", "user equipment", "CPE", etc. are used as an object to communicate with a base station, but communication with a base station can be performed using a super frame structure according to the present invention. As long as there is no need to be bound by these terms, any subject may correspond.

On the other hand, in some cases, well-known structures and devices are omitted in order to avoid obscuring the concepts of the present invention, or shown in block diagram form centering on the core functions of each structure and device. In addition, the same components will be described with the same reference numerals throughout the present specification.

The present invention proposes a super frame structure for receiving a continuous communication service from a base station by terminals having different capabilities, that is, narrowband mode or wideband mode, based on CR. That is, a method of configuring a super frame is a method of basically allocating a frame structure within a super frame to an area for a narrow band terminal, and allowing the broadband mode terminal to receive a service.

In addition, as described above, the location information is included in the FCH and / or MAP information in the super frame in order to inform the terminal entering the middle of the super frame period of the location of the resource region for the narrowband terminal. Herein, the FCH and MAP information unit includes information on the corresponding frame. Hereinafter, for convenience of description, the FCH and MAP information unit will be collectively defined as a "header unit" of the unit resource region. In addition, "unit resource region" herein refers to a resource region included in a block divided by one channel and one frame in the super frame.

On the other hand, including the location information may be the FCH and / or MAP information unit of all the unit resource region in the super frame, to be inserted only limited to the FCH and / or MAP information unit of the unit resource region belonging to the resource region for the narrowband terminal. It may be, and may vary according to each embodiment.

Hereinafter, as an embodiment satisfying the above-described general requirements, 1) a method for classifying whether a narrowband mode is supported based on a channel region, 2) a method for classifying based on a time domain, and 3) a method for classifying a channel and a time domain How to do this will be described with reference to the drawings.

8 is a diagram illustrating a super frame structure such that at least one or more channel regions support narrowband mode user equipment (UE) in accordance with one embodiment of the present invention.

Even if the frequency band allocated to the super frame is wideband except for the frequency band already used (indicated by "occupied by incumbent" in FIG. 8), at least one channel is configured to be used by a narrowband mode terminal. Since the broadband mode terminal can also be serviced in the area where the narrowband mode terminal can be serviced, this is also an area where the narrowband mode and the broadband mode can be synchronized. In this way, the frame is configured to enable the broadband service except for the region where the narrowband mode and the wideband mode are simultaneously available. In FIG. 8, the location of a channel capable of serving a narrowband terminal and a wideband terminal as shown by channel t + 1 may be known through FCH and / or MAP information in a frame. In addition, when the position information of such a channel is inserted into the above header part of all the unit resource regions included in the above-described channel region, even if the terminal enters the network at any time within the super frame period, which channel is in the narrowband mode. It is more preferable because it can know whether the channel supports the.

The structure of the super frame shown in FIG. 8 is not limited to a specific channel position and size except for allocating one or more channels for a narrowband mode terminal. However, a frame including a quiet period for in-band sensing in which the terminal or the base station searches for a band not used by previous users (for example, frame m- in FIG. 8). Channel 2) does not allocate a channel interval for such narrowband mode communication as shown in FIG. In addition, according to an embodiment of the present invention, the multi-channel mode and the single channel mode do not have to provide the same service at the same time, and the silent periods can be set at different times. In other words, in generating the silent period, the silent period of the multi-channel mode and the silent period of the single channel mode need not be given at the same time unless the frames of the two modes are contiguous on the physical channel.

Meanwhile, location information of one or more channels for providing a service to a narrowband mode terminal as described above may be additionally inserted into a super frame control header (SCH). In this case, when the SCH is used in the same form in all channel regions, it is not necessary to insert different information in every channel, so that there is an advantage that it is easy to implement and there is no need to repeat the common items in all channels, but all channels Since it is necessary to include "list information" indicating whether the narrowband mode is supported for the number of bits may be increased. On the contrary, if the SCH is different for each channel, the number of bits required to indicate whether each channel supports narrowband mode is reduced, but there is a drawback that the common content of all channels must be repeatedly inserted. This can be somewhat complicated. By additionally inserting the location information of the narrowband mode supporting channel into the SCH, the base station can more stably transmit the location of the channel region supporting the narrowband mode terminal, and the narrowband mode terminal is also narrowband within the entire superframe. The position of the mode support channel can be obtained stably.

Hereinafter, a method of concretely implementing such a super frame structure will be described.

In a case where the channel supporting the narrowband mode is not changed and one or more channels are continuously used in the narrowband mode in the super frame, the SCH is described in Table 1 or Table 2 below. It can be configured together. Of course, as described above, even when the information on the channel supporting the narrowband mode is included only in the header of the unit resource region of the corresponding region, the terminal entering the middle of the super frame may determine the location of the channel supporting the narrowband mode. However, the information may be more stably transmitted by including the corresponding information in the SCH. In addition, Table 1 illustrates a case where the same SCH is applied to all channels, and Table 2 illustrates a case where a different SCH is applied to each channel.

In Tables 1 and 2, Table 1 shows a case where a common SCH is used for all channel regions. The "Narrow band Number List" column includes information on whether all channels support narrowband mode. While bits are allocated, Table 2 shows a case where a different SCH is inserted for each channel. As shown in Table 1, the narrow band mode of the channel is supported in the "Band Type" column without the "Narrow band Number List" column. It is different in that one bit for indicating whether or not is allocated.

As shown in Table 1 and Table 2, the SCH designates a channel number for the narrowband mode and indicates whether the corresponding frame is a narrowband type in each frame. As described above, the location information described above may be included in the FCH and / or DL-MAP information unit of each unit resource region, that is, each frame included in the corresponding channel. Table 3 below is an example of the case of being included in the DL-MAP. Indicates.

That is, as shown in Table 3, when the channel information supporting the narrowband mode is transmitted using the DL-MAP, the channel including the channel information supporting the narrowband mode CPE when the " Band type " indicates " 1 " , If "0" indicates that this channel does not support narrowband mode CPE, this means that the UE knows which channel supports narrowband mode even when the UE enters the network during the super frame period. Can be obtained.

Meanwhile, a method of communicating between a base station and a terminal using a super frame having such a structure will be described below.

In the communication method according to an embodiment of the present invention, when the base station communicates using a super frame for allowing one or more channels to support a narrowband mode as described above, the base station informs the terminal of the channel area to inform the terminal of the channel area. This location information is inserted into the unit resource region of ie, the FCH and / or DL-MAP information of the frame. In addition, the UE may acquire such a channel location through the FCH and / or DL-MAP as well as the SCH of the super frame, thereby providing a seamless communication service to a narrowband mode terminal entering the network in the middle of the super frame. Can provide.

Meanwhile, the base station may additionally insert the location information of the narrowband mode support channel into the SCH as well as the header of the unit resource region described above. In this case, when all channels have the same SCH, the narrowband of each channel is included in the SCH. If a list of mode support is inserted, and if a different SCH is inserted into all channels, whether a narrowband mode of each channel is supported may be inserted. In addition, using the super frame structure as described above, the base station may operate in various ways to efficiently communicate with the terminal for the narrowband mode, which will be apparent to those skilled in the art from the above description.

Hereinafter, as the second of the embodiments of the structure of the super frame for providing a seamless communication service to the narrowband terminal in the present invention, an embodiment for dividing whether the narrowband mode is supported based on time will be described.

FIG. 9 is a diagram illustrating a super frame structure such that at least one frame region supports a narrowband mode UE in accordance with an embodiment of the present invention.

In FIG. 9, one or more frame regions for supporting the narrowband mode terminal are indicated by diagonal lines. In this method, a narrowband mode terminal designates a frame for receiving a service through the FCH and / or MAP of the frame. By indicating whether the frame supports the narrowband mode on the FCH and / or MAP of each frame, the terminal entering the network within the super frame period may identify a frame supporting the narrowband mode. However, unlike the case of FIG. 8, in which one channel region continuously supports the narrowband mode, when one or more frames are configured to support the narrowband mode, a frame section supporting another narrowband mode in the previous frame region is designated. It is preferable to obtain the frame position more stably. In this case, a frame in which the first narrowband mode is supported may be designated by the SCH, and a frame in which the next narrowband mode is supported may be specified in a frame in which each narrowband mode is supported. As in the case of FIG. 8, at least one frame for a narrowband mode terminal exists in one superframe, and the narrowband mode terminal may receive a service only in a narrowband, whereas the narrowband mode terminal may receive a service. The band can also be serviced by the terminal in the broadband mode

Hereinafter, a method of concretely implementing such a super frame structure will be described.

As described above, the frame region itself may be implemented to indicate whether the frame region itself supports the narrowband mode, but as shown in Tables 4 and 5 below, the narrowband may be narrowed in the frame that supports the first narrowband mode. It is more preferable to indicate the period and frame number until the next frame in which the band mode is available. Tables 4 and 5 show downlink interval usage codes (DIUCs) and corresponding narrowband IE formats, respectively, as information elements (IEs) included in the DL-MAP.

DIUC Usage 0 Self-Coexistence (Active Mode) One Self-Coexistence (Passive Mode) 2-12 Burst profiles 13 PAPR Reduction 14 End of map 15 Extended DIUC

Syntax size Notes DS_Extended_IE () { Extended DIUC 4 bits 0x00 Length 4 bits Frame number 8bits Represents the next single mode frame number used by the BS. Duration from the previous Narrow band Frame 16 bits Duration from previous narrowband frame. }

As shown in Table 5, the DL-MAP of a frame supporting narrowband mode indicates the number of the next single-mode frame used by the BS by dedicating 8 bits of information to the "Frame Number" item, and "Duration from the previous". Narrow band Frame "field is assigned 16 bits of information to indicate the duration from the previous narrowband frame. As such, by inserting information about a frame supporting the next narrowband mode, the narrowband mode terminal that enters the network within the superframe period does not wait for the next superframe for communication with the base station, but immediately next narrowband mode frame period. You can get services at

Meanwhile, a method of communicating between a base station and a terminal using a super frame having such a structure will be described below.

In the communication method according to an embodiment of the present invention, when the base station communicates using a super frame that allows one or more frames to support a narrowband mode as described above, the base station informs the corresponding frame area to inform the terminal of the frame area. This location information is inserted into the unit resource region of ie, the FCH and / or DL-MAP information of the frame. In addition, the UE may acquire such a channel position through the FCH and / or DL-MAP as well as the SCH of the super frame, thereby providing a seamless communication service to a narrowband mode terminal entering the network in the middle of the super frame. Can be provided.

Meanwhile, the base station may additionally insert the location information of the narrowband mode support channel into the SCH as well as the header portion of the unit resource region described above. It is desirable to be able to deliver to the mode terminal.

Next, as a third embodiment of a structure of a super frame for providing a seamless service to a narrowband terminal in the present invention, an embodiment of dividing whether narrowband mode is supported based on both time and channel will be described. do.

FIG. 10 is a diagram illustrating a super frame structure in which an area distributed in a predetermined channel area and a predetermined frame area is set as an area supporting a narrowband mode UE according to an embodiment of the present invention.

Unlike a super frame that sets one or more channel regions that support the narrowband mode as shown in FIG. 8, and a super frame that sets one or more frame regions that support the narrowband mode as shown in FIG. 9, a frame that supports the narrowband mode and We propose a super frame structure in which a channel is changed. That is, at least one unit resource region supporting the narrow band mode as indicated by the diagonal line in FIG. 10 includes the frame 1 region of the channel t + 1 region, the frame m-1 region of the channel t-1 region, and the channel. Like the frame m region of the t + 1 region, they are distributed in a predetermined channel and frame region.

In this case, as in the case of setting one or more narrowband mode frame regions shown in FIG. 9, the superframe period is made to indicate whether the unit resource region itself is a region that supports the narrowband mode in each unit resource region. The terminal entering the network may check the unit resource region supporting the narrowband mode. However, as in the embodiment shown in FIG. 9, since the narrowband mode support resource region shown in FIG. 10 does not continuously exist in one channel, the next narrowband support unit resource region in the previous narrowband support unit resource region It is more desirable to give information about. In this case, a frame or channel that supports the first narrowband mode is informed by the SCH, and a method of designating the next frame or channel in a frame that supports the first narrowband mode is preferable.

On the other hand, the following describes how to implement such a super frame structure in detail.

Hereinafter, the structure of the super frame inserts the position information of the narrowband mode support unit resource region into the SCH and the FCH and / or MAP region of each frame among the above-described embodiments, and inserts the position information into the FCH and / or MAP region of each frame. Location information of the narrowband mode support unit resource zone to be described will be described based on an example of information on the next narrowband mode support unit resource zone. In such a case, if the SCHs of all channels are the same, a "list of channels and frames" supported by the narrowband mode may be indicated. On the other hand, when the SCHs of all the channels are different from each other, only the "list of frames" supporting the narrowband mode included in the corresponding channel need be known. Such cases are shown in Tables 6 and 7 below, respectively.

As can be seen in Table 6 and Table 7, in the case of Table 6 showing a common SCH for all channels, both the "Narrow band Number" item and the "Frame Numbers" item in the part indicating the narrow band mode support unit resource region While a list of channels and frames supporting narrowband mode is provided by allocating 8 bits of information, the "Frame Numbers" item in the section indicating a narrowband mode supporting unit resource region in Table 7 showing a different SCH for each channel. Only 8-bit information is allocated to provide a list of frames that support narrowband mode.

On the other hand, after specifying a channel number and a frame number capable of a narrowband mode as described above in the SCH, each frame starts from a channel or frame supporting the first narrowband mode as shown in the narrowband IE format shown in Table 8 below. It informs the channel number and the period or frame number for the first narrowband mode.

As shown in Table 8, according to this embodiment, the number of the next narrowband channel used by the BS is informed using 8 bits of information in the "Channel Number" item, and 8 bits of information in the "Frame Number" item. The number of the next narrowband frame used by the BS is informed by using, and the duration from the previous narrowband frame is informed by using 16 bits of information in the "Duration from the previous Narrow band Frame" item. Compared with Table 5 in the embodiment of the super frame structure for setting one or more frame regions to support narrowband mode, Table 8 does not only convey the frame number of the next narrowband mode support frame, but the next narrowband. The number of the mode support channel is also different in that it is known because the resource region supporting the narrowband mode in the super frame structure according to the present embodiment is changed not only in the frame region but also in the channel region.

Meanwhile, a method of communicating between a base station and a terminal using a super frame having such a structure will be described below.

In the communication method according to an embodiment of the present invention, when the base station communicates using a super frame including a resource region supporting a predetermined frame and a narrowband mode distributed in the predetermined channel region as described above, this resource region This location information is inserted into the FCH and / or DL-MAP information of the frame of the unit resource region of the corresponding resource region to inform the UE. In addition, the UE may acquire such a channel position through the FCH and / or DL-MAP as well as the SCH of the super frame, thereby providing a seamless communication service to a narrowband mode terminal entering the network in the middle of the super frame. Can provide.

Meanwhile, the base station may additionally insert the location information of the narrowband mode support channel into the SCH as well as the header portion of the unit resource region described above. It is desirable to be able to deliver to the mode terminal.

In the super frame structure according to the above-described three embodiments, the information contained in the SCH and the frame may be divided as follows.

Preamble SCH (Super Frame Control Header) ＊ System type ＊ Channel information-Channel number-Type (narrowband / broadband)-Number of channels ＊ Frame number and size ＊ Silent period schedule (start time, duration) frame ＊ Preamble ＊ FCH (Frame Control Header):-Size of DL and US-MAP-Channel descriptor-PHY characteristics-Channel information (current channel (frame) type & time to next narrowband channel (frame)-> DL- May be included in the MAP * DL / UL-MAP * Burst * UCS (Urgent Coexistence Situation): Incumbent detection report * Bandwidth request * SSS (Sliding Self-Coexistence Slots)

In general, the information indicated by Table 9 is limited to the case in which channel information for supporting services of UEs having different capabilities is included in both an SCH and a frame. .
